'resentc fore been proposed to connect the return cm cuit with a neutral point of the source and use p y h ctro metivesfcm in one direction. -By cetol .2,itwillbe flow o e more or less ulsating, due to the rise and fall-of. t he' eectromotive-ioroc applied to one device efore the succeeding wave is transmitted through the successive device.

In the diagram ig. 2, the curves marked 30, 82, 34, would represent diagrammatically the flow of one y if the positive impulses alone were emp oyed, whereas when the l negative impulses are also employed the flow of one due to the negative impulses, represente Iy the curves 3], 33 and 35, so that thgrehulting flow of energy will be rcpj' the c nfiguration of the upper curve of Fig. 2, This I resented in the diagram by the heavy lines.

W l bc'understood that the diagram indicating the time curves of the 'electro-mofiv -f r m is theoretical and that the relaive positions and relations of the waves may bemore or loss modified by inductive and other effects. It will also be understood that the arrangement herein shown and described is ap licable to supply circuits of any number of '1) secs, andalso to a pluralit of V supply circuits, either in or out of sync selected for pu l gas or vapor msm. e i

It hasb'een'convenient to describe the sysinolosed tom ofdistribution herein disclosed no embodying, among its princi ,al features, a gas or vapor electrical appam us of the general character of the (loo r Howl will be understood that this device has been uses of illustration, and that the invention, adlg3 is not to the enzployment of a dov of that specific charac er.

It is found convenient to design to those c devices which are mm as positively connected devices and those vi es connected to the negative side of the 9, 1908, Serial nergy will bels devices containing an incl or convenience is rep-.

were effectively employed. It has heretoi work circuit as fnegatively connected" dovloes. In a divisional gpplication, filed September umber 452,241, claim is made to certain other features of the system herein described.

claim as my invention:

1. The combination with a source of alternating electric currents, of an inclosed gas or vapor, a, work circuit, multiple'positive electrodes and a single negative electrode, connections from the several positive electrodes with: the respective alternating current do, a connection from the negative electrade to one side ofawork circuit, multiple gasor vapor each having one e ctrode connected with the negative side of the work circuit and the rc-f malning electrodes connected with tho 119-. spective alternating current/leads, and-means for providing a continuous flow otcurrent in a -given direction through each of said vices.

2. The combination with a source of threephase alternating currents, of a work circuit, an inclosedcgas or vapon-three positiveelec trodes and a single negative electrode therein,- connections from the several positive electrodes with the respective alternating a connection from the negative electrode to one side of said work circuit, with multiple devices each including an gas or va r and each having one with the other side of tits with one of the alternating current leads, together with means for providing a continuous flow of current in a given direction through each of said devices.
